Pinpoint Test F: The Doors Do Not Lock/Unlock Using The Remote Keyless Entry (RKE) Transmitter: Testing

WARNING: This page is about a different car, the 2005 Mercury Montego, 2005 Ford Freestyle, and 2005 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: All RKE transmitters must be present to begin diagnosis of the RKE system.

NOTE: Aftermarket or dealer-installed systems may adversely affect the RKE system operation. These systems should be disconnected before diagnosing any RKE concerns.

F1 CHECK FOR THE CORRECT RKE TRANSMITTERS
- Check that the correct RKE transmitters are used with the vehicle.
  - Make sure the RKE transmitters are those provided with the OEM system and not from an aftermarket system or a dealer-installed system.
- Are all the correct RKE transmitters present?
- Yes : GO to F2.
- No : The system cannot be tested without the correct RKE transmitters. INFORM the customer that all the correct RKE transmitters need to be present to proceed with diagnosis of the system.
F2 CHECK THE OPERATION OF THE RKE TRANSMITTER WITH THE KEY IN THE OFF POSITION
- Key in OFF position.
- Check the operation of the RKE transmitter.
- Does the system operate correctly now?
- Yes : The system is operating correctly. INFORM the customer of the correct vehicle operation.
- No : Go to F3.
F3 CHECK THE POWER DOOR LOCK SYSTEM FOR CORRECT OPERATION
- Verify the door lock/unlock operation by actuating the LH front door lock control switch.
- Do all the doors lock and unlock correctly?
- Yes : GO to F4.
- No : GO to PINPOINT TEST C .
F4 CHECK FOR THE COMPLETE FUNCTIONALITY OF THE RKE TRANSMITTER(S)
- Check all the RKE transmitter buttons for correct operation.
- Does the panic button operate correctly?
- Yes : REPLACE the inoperative RKE transmitter. PROGRAM all RKE transmitters. REFER to REMOTE KEYLESS ENTRY TRANSMITTER PROGRAMMING . INFORM the customer that any RKE transmitters not present need to be reprogrammed. CLEAR the DTCs. TEST the system for normal operation.
- No : GO to F5.
F5 MAKE SURE THE RKE TRANSMITTER SIGNAL IS BEING RECEIVED
- Connect the diagnostic tool.
- Enter the following diagnostic mode on the diagnostic tool: Smart junction box (SJB) function tests, transmitter test, or program transmitter.
  Monitor the remote transmitter identification code (TIC).
- Verify the RKE transmitter signal is being received. Press a button on the RKE transmitter while observing the diagnostic tool.
- Does the TIC show up on the diagnostic tool screen when a button is pressed?
- Yes : GO to F6.
- No : GO to F7.
F6 CHECK IF THE RKE TRANSMITTERS ARE PROGRAMMED
- Enter the following diagnostic mode on the diagnostic tool: Enter the SJB function tests, transmitter test or program transmitter.
  Monitor the remote transmitter TIC/DATA.
- Note the TICS programmed to the vehicle.
- Does the TIC displayed under current RKE transmitter match any of the TICs stored in memory?
- Yes : GO to F8.
- No : PROGRAM all of the RKE transmitters. REFER to REMOTE KEYLESS ENTRY TRANSMITTER PROGRAMMING . INFORM the customer that any RKE transmitters not present need to be reprogrammed. CLEAR the DTCs. TEST the system for normal operation.
F7 CHECK THE RKE TRANSMITTER BATTERY
- Using a thin coin, open the RKE transmitter.
- Do not clean off any grease from the battery terminals on the back surface of the circuit board.
- Verify the correct battery is used (CR2032).
- Remove the RKE transmitter battery and measure the voltage.
- Is the voltage greater than 2.5 volts?
- Yes : GO to F9.
- No : INSTALL a new battery (be sure the battery is seated correctly). DO NOT reprogram the RKE transmitters (faulty or dead batteries do not erase TICs from memory). CLEAR the DTCs. TEST the system for normal operation.
F8 CHECK IF THE RKE TRANSMITTER IS OUT OF SYNCHRONIZATION WITH THE SJB
- The vehicle must be unlocked electronically through the RKE transmitter or the door lock control switch prior to using any diagnostic tools.
- Retrieve the continuous DTCs with the diagnostic tool.
- Is continuous DTC B2425 stored in the SJB?
- Yes : GO to PINPOINT TEST J .
- No : GO to F9.
F9 CHECK FOR NORMAL OPERATION WITH A KNOWN GOOD RKE TRANSMITTER
- Enter the following diagnostic mode on the diagnostic tool: Enter the SJB function tests, transmitter test or program transmitter.
  Monitor the remote transmitter TIC/DATA.
- Using the customer's second RKE transmitter, or a known good RKE transmitter that is correct for the vehicle, verify the RKE transmitter signal is being received by the SJB.
- Does the TIC show up on the diagnostic tool when a button is pressed on the RKE transmitter?
- Yes : REPLACE the inoperative RKE transmitter. PROGRAM all RKE transmitter(s). REFER to REMOTE KEYLESS ENTRY TRANSMITTER PROGRAMMING . INFORM the customer that any RKE transmitters not present will need to be reprogrammed. CLEAR the DTCs. TEST the system for normal operation.
- No : GO to F10.
F10 CHECK THE SJB FOR CORRECT OPERATION
- Disconnect all the SJB connectors.
- Check for:
  - corrosion
  - pushed-out pins
- Connect all the SJB connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
- Yes : INSTALL a new SJB. REFER to MULTIFUNCTION ELECTRONIC MODULES . REPROGRAM all RKE transmitters. REFER to REMOTE KEYLESS ENTRY TRANSMITTER PROGRAMMING . INFORM the customer that any RKE transmitters not present need to be reprogrammed. TEST the system for normal operation.
- No : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test.
